Question

Find the mean of the first five even whole numbers

Answer 1

$\textbf{\underline{\underline{Answer :-}}}$

The mean of the first five even whole numbers is 4.

$\textbf{\underline{\underline{Explanation :-}}}$

Whole numbers are the numbers from 0,1,2,3,4,5,6......... (and so on)

Even numbers are the numbers divisible by 2 (no remainder is left)

$\star$First five even whole numbers =

• 0

• 2
• 4

• 6

• 8

Zero is an even number because it has all characteristics of being an even number. ( 0 ÷ 2 = 0 )

$\star$ As we know :

${\boxed{\sf \: {Mean = \frac{Sum \: of \: observations}{Total \: observatoins} }}}$

$\sf{\implies} Mean = \dfrac{0 + 2 + 4 + 6 + 8}{5}$

$\sf{\implies} Mean =\dfrac{20}{5}$

$\sf{\implies} Mean = 4$

$\boxed{\red{\sf{Mean = 4}}}$

$\therefore$ The mean of the first five even whole numbers is 4
